I'm not really sure what's helpful when people post self deprecating or negative statements about themselves in posts like these.

Sometimes it feels like it is in the neighborhood of phishing, like a veiled attempt to encourage responses that say the opposite of whatever bad thing the OP thinks about herself.

But I am truly confused about what would be helpful to you or what I"m supposed to pay attention to. I think that your T's actions are very sweet, but hardly some kind of extraordinary kindness, even for T's. It's not as if she sent you on a free vacation, or comp'd her therapy. It's a gesture that communicates caring, but that can also be communicated verbally. I think that I would probably find such a card as over the top and weird, but I'm not really a sentimental person.
